Introduction of Cone Crusher:
Hongji Mine Machinery cone crusher is a machine used forr breaking the big rocks into the minor rocks, gravels or rock dusts. It is widely used for medium and fine crushing all kinds of rocks with pressure under 350MPa in mining, cement industries, sand industries and other areas. The perfect combination of high-performance crushing chamber and high crushing frequency improves the handling ability of the cone crusher to a great degree.
Technological Development of Cone Crusher:
The design process of cone crusher has always been slow, which has lasted for almost 60 years. Some reliable productions have been used for reference in the basic design of cone crushers. The greatest changing lies in the improvement of rotating speed. For example, a 48-inch (120 cm) Cone Crusher in 1960 can produce 170 tons of gravels per hour, while the cone crusher with the same size today can produce 300 tons per hour.
The improvements come from the enhancement of speed, as well as some better design of crushing cavity. Another great development of cone crusher exists in the application of hydraulic techniques, which can prevent the uncrushed materials from getting into the crushing cavity. The uncrushed materials such as steel can cause great damage and more cost to the crusher when getting into the cavity. The development of hydraulic cone crusher reduces much downward time and prolongs the life of these machines.
Hongji Mine Machinery has always been the greatest cone crusher manufacturer and supplier with complete specifications, which enables us to fulfill users' various needs.
Stucture of Cone Crusher:
Cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.
Working Principle of Cone Crusher:
When the cone crusher is working, the engine rotates around a fixed point through the belt wheel or the coupling, meanwhile the transmission shaft and the conical part of the cone crusher are taken under the force of the eccentric bushing, which makes the crushing wall close to the pierced mortar wall at intervals. Then, the ores will be impacted, squeezed and bent constantly in the crushing chamber, resulting in the crushing of the ores.
